ROCK-BREAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 510,800,'date dDecember 12,1893.

Application filed August 15,1292. Serial No. 443,065. (nomad) erencebeing had tothe accompanying drawings, in which Figure 1 is alongitudinal vertical section on line 1-1 of Fig. 2. a Fig. 2 is ahorizontal section on line 2-2 of Fig. 1. Fig. 3 is a detail, being apartial sectional view on line 3 3 of Fig. 1. Fig. 4 is a perspectiveview of one of the face plates. Fig. 5 is an elevation of one side ofthe upper portion of the oscillating lever; and Fig. 6 is a detail,being a'view of the back of one of the face plates carried by theoscillating lever. My invention relates to machines for crushing ore orrock, and the object of my inventron is to improve the construction andoperatron of machines of that class. I accomplish this object ashereinafter specified and as illustrated in the drawings.

In the drawings, the numeral 7 indicates the outer casing of the machinewhich is of suitable size and shape, and is formed or constructed with acentral partition or wall 7, which may, if desired, terminate in acurved lower edge, as at 7". The levers 8 are vertically mounted in thecasing 7 at opposite sides of the partition or wall 7 each lever havingits upper end supported by trunnions 9 and 10 resting in suitablebearings at the upper portions of the casing and partition or wall. Thelower portion of each lever S is preferably bifurcated, consisting oftwo parallel arms connected by cross ribs 11; but the lever may be madeof a single piece if desired. By trunnioning the lever 8' as abovedescribed, it is adapted to be oscillated, as will be hereinafter setforth. The two sides of the upper portion of the lever 8 which areninety degrees from the trunnions 9 and 10 are oppositely inclined, asshown in Fig. 1, and are provided with dove-tailed grooves 12, as bestshown in Fig. 5.

13 indicates face plates, each of which is provided with a tongue 14adapted to fit into the grooves 12 in the lever 8. The lower portionsofthe grooves 12 are somewhat narrower than. the upper portions, toprevent the plates '13 from moving down too far. By this constructionthe plates 13 may be readily fitted in place on the lever 8.

15 indicates face plates which are mounted upon the upper portion of thecasing 7, opposite the face platesl3. The inner'surfaces of, the faceplates 15 are curved, being preferably of aboutthe shape shown in thedrawings. The rear surface of each of the plates 15 is adapted to fitsnugly against the inner surface of the casing ,7 at the point where itis adapted to be secured thereto, as shown in Figs. 1 and 3. Each of theface plates 15 is provided near its lower end with a dove-tailed groove16, which extends vertically, as shown in Fig. 1. The grooves 16 areadapted to receive the dove-tailed heads of bolts 17, which pass throughthe side of the casing and carry nuts 18 upon their outer ends. By thisconstruction, by tightening the nuts 18 upon the bolts 17, the plates 15maybe tightly held in place on the casing.

19 indicates a lug formed on the back of each plate 15, which lug isprovided with an inclined upper surface, as shown. The plates 15 arealso provided with recesses 20 immediately above the lugs 19; theobject. of which will be hereinafter set forth. The casing 7 is alsoprovided with recesses 21, which are of such shape as to receive thelugs 19, and also to receive a nut 22 which is mounted upon a bolt 23,as shown in Fig. 1. The bolts 23 pass through the casing 7, projectinginto the recesses 21. The lower edge of each nut 22 is inclined toconform to the inclination of the adjacent lug 19 upon which it isadapted to rest. By loosening the nut 18 on the bolt 17, and operatingthe bolt 23, the nut 22 will be moved upon its bolt, thereby moving inor out upon the lug 19. If the nut 22 is moved toward the plate 15, theplate may be raised a short distance, or if it is moved in the oppositedirection it will force the plate 15 downward. By this construction theposition of the plates 15 may be adjusted as desired to compensate forwear and to vary the operative position of said plates15 with relationplates 15 are preferably provided with staples to the plates 13 on theoscillatory lever. The

24 at theiiupper ends, adapted to receive hooks or other implements tofacilitate their removal.

The plates 13 and 15 are so placed with relation to each other that byoscillating the lever 8 the stone or ore which may be thrown betweenthem from above will be crushed, and will thence pass downward betweenthem.

25 indicates chutes, the upper ends of which lie immediately beneath theface plates 13 and 15, their lower ends terminating at the outside ofthe casing 7.

The leversSare both oscillated by means of a single shaft 26, which istransversely mounted in the lower portion of the casing 7, and carrieseccentrics 27 which are connected to the lower ends of the levers byconnecting rods, as at 28. The shaft 26 may be rotated by any suitablemechanism, and through the medium of the eccentrics and connecting rodsthe levers 8 will be oscillated. By constructing the casing with thecentral partition or wall 7 the levers and coacting crushing heads areseparated, and the machine can be economically manufactured, as itsweight is greatly reduced without diminishing its capacity. Any numberof levers may be arranged within a single casing, partitions beingintroduced between the different crushing devices and two double sets ofcrushing devices arranged in juxtaposition to form a double machine inwhich each oscillatory lever carries two face plates 13, one on eachside, and is arranged between and opposite the face plates 15 attachedto the machine casing.

The faces of the face plates 13 and 15 are preferably corrugated, asshown, and the plates are preferably of the shape shown in the drawings;but plates of other shape may be used if desired.

It will be observed that each set or pair of crushing devices leadsdirectly to one of a series of inclined chutes having their lower endsterminating outside the casing on opposite sides of the machine, therebyproviding a double delivery of the crushed material.

The casing 7 is constructed to inclose the oscillatory lever 8 and itsoperating mechanism which is located within the lower part of saidcasing as shown in Fig. 1. The upper portion of the casing 7 is providedwith surrounding ledges or flanges 29 that are provided with recesses30, Fig.2, or otherwise adapted to receive and support the timbers forforming a platform to be built around and upon a level with the upperpart of the casing, thereby permitting the unloading of materialimmediately into the crusher.

That which I claim as my invention, and desire to secure by LettersPatent, is-

1. The combination of a casing having a vertical partition or wall, anoscillatory lever pivotally suspended at each side of the partition orwall, the face plates 13 and 15 attached respectively to both sides ofeach lever and to the opposite inner sides of the casing, and a singleshaft connected with and operating the levers, substantially asdescribed.

2. The combination of a casing 7 having a central vertical partition orwall 7, an oscillatory lever 8 pivotally suspended at each side of thesaid partition or wall, the face plates 13 secured to opposite sides ofeach lever, the face plates 15 secured to the casing at opposite sidesof the said partition, a single shaft 26 provided with eccentrics 27,and connecting rods 28 between the eccentrics and the levers, wherebythe levers are oscillated by a single shaft, substantially as described.

3. The combination with a casing, and crushing mechanism, of a faceplate 15, having a lug 19, said lug having an inclined upper surface, arecess 21 in said casing, bolt 23, having a nut 22, said nut having aninclined under surface adapted to rest upon the upper surface of saidlug, and means for securing said plate upon the casing, substantially asdescribed.

4. The combination with a casing, and crushing mechanism, of a plate 15,having a lug 19 and a groove 16, a bolt 17 projecting through said casing into said groove 16, said bolt having a head adapted to fit into saidgroove 16, bolt 23, nut 22 carried thereby, and a recess 21 in saidcasing adapted to receive said nut 22, the said lug 19 and the nut 22being provided with inclined surfaces in contact with each other,substantially as and for the purpose specified.
